The continuous measurement of jugular venous oxygen saturation (SjvO2) with a fiberoptic catheter is evaluated as a method of detecting cerebral ischemia after head injury. Forty-five patients admitted to the hospital in coma after severe head injury had continuous and simultaneous monitoring of SjvO2, intracranial pressure, arterial oxygen saturation, and(More)
The traditional practice of elevating the head in order to lower intracranial pressure (ICP) in head-injured patients has been challenged in recent years. Some investigators argue that patients with intracranial hypertension should be placed in a horizontal position, the rationale being that this will increase the cerebral perfusion pressure (CPP) and(More)
A patient with a free-tissue transfer to the lower leg underwent amputation three months post-operatively. The amputated limb and the free flap were evaluated angiographically immediately following amputation. Vascular injection of the extremity, with clamping of the pedicle, demonstrated that the area of the flap was devoid of radiopaque vessels, and(More)
